Description
Erūca Crawford is a supporting character in the anime series who serves as the energetic and caring younger stepsister of the protagonist, Allen Crawford. She is a young woman, notably the same age as the female lead, Charlotte Evans.

Erūca came to be part of the Crawford family after losing her own parents, a difficult experience that shaped her deep appreciation for her new family. Her primary motivation stems from a desire to look after those she cares about, particularly her stepbrother. From a young age, she made it her mission to cheer up the grieving Allen, persistently challenging him to games in a determined effort to make him smile again. This same nurturing and slightly mischievous spirit extends to other characters she meets.

In both appearance and personality, Erūca is lively and playful. She is almost never seen without her signature hoodie featuring cat ears, a fashion choice that reflects her fun-loving and energetic nature. Her personality is a blend of kindness and a touch of naughtiness; she is friendly and energetic, always looking out for others, but also enjoys a bit of mischief. This mischief is always rooted in genuine warmth, as she loves helping other girls, like Charlotte, discover the joys of fashion, friendship, and other fun, sometimes slightly forbidden, activities.

Erūca’s primary role in the story begins when she visits Allen with the initial intention of bringing him back home. Upon arriving, she is surprised to find Charlotte living with him. Rather than leaving, she quickly takes an interest in the disgraced noble lady and decides to stay, introducing her to a more carefree and girlish side of life. This leads to a friendly but spirited competition with Allen, where the siblings challenge each other to see who can teach Charlotte the most naughty things during a day out in town.

Beyond her relationship with her stepbrother, Erūca forms key bonds with other characters. She becomes close friends with Charlotte, acting as a confidante and a guide to a more exciting world. She also frequently schemes with another character, Miacha, to create situations that encourage Allen and Charlotte’s relationship to develop further, such as arranging for them to visit a lovers' retreat. Through these actions, Erūca demonstrates consistent development by shifting from someone who simply wants to bring her brother home to an active supporter of his new life and his relationship with Charlotte, all while maintaining her cheerful and caring disposition.

Beyond her social qualities, Erūca holds the official position of an apprentice magic engineer. She is in the process of learning to create and utilize magical tools, and she becomes genuinely excited whenever she encounters a new or unusual magical item. She takes this role seriously but pursues it with her characteristic playful style, adding a unique dimension to her capabilities within the story's world.
